Fixes #6417.

Changes in this commit:

- Set the --lib flag so that the benchmark works for packages with libraries or
  executables.
- Set --ignore-project to prevent cabal projects from affecting the results.
- Handle four types of cabal errors that were introduced by v2-install.
- Use +nowrap to simplify parsing of cabal errors.

Improve few internalErrors in InstallPlan

Resolve #6355: Fix most incomplete-uni-patterns

Or replace

    Just foo = rhs

with

    foo = fromMaybe (error "...") rhs

which there are plenty. I didn't tried to refactor these errors away,
let cabal panic, if it hits them.

Implement cabal install -z

Resolve #5919
Resolve #6410

Add `withProjectOrGlobalConfigIgn` to unify the behaviour with `-z` in `cabal
repl`

This speed ups the first installation,
and also (probably) wastes less hard drive space.

Bump version 3.3

Herbert Valerio Riedel authored 6 years ago and Oleg Grenrus committed 5 years ago

These are only supported properly starting with
cabal-version:3.0 (which has been enforced by
Hackage as well -- via this very patch).

See #6033 for details

Normalise ghc args 8.10

Sergey Vinokurov authored 5 years ago and Oleg Grenrus committed 5 years ago

I.e. don’t rebuild everything when a ghc flag that affects how error
messages are presented is added.

IOData improvements and faster ghc-pkg dump parsing

Takenobu Tani authored 5 years ago and Oleg Grenrus committed 5 years ago

These extensions already landed in master and ghc-8.10 branch:
  * CUSKs
  * ImportQualifiedPost
  * StandaloneKindSignatures
  * UnliftedNewtypes

Please see also:
  * https://gitlab.haskell.org/ghc/ghc/blob/master/docs/users_guide/8.10.1-notes.rst
  * https://gitlab.haskell.org/ghc/ghc/blob/master/testsuite/tests/driver/T4437.hs

Parsing the `ghc-dump` is now two times faster and uses less memory.
For big cabal nix-stores this speedup is noticeable:

Also improve the `process` wrapper. Now ignores SIGPIPE.

Structured binary

It defines `Structured` type class, which we use to prepend
a hash to cached `Binary` blobs. Thus we can catch early, if
format is changed, avoiding corrupt cache making cabal
behave weirdly.

Plenty types got Typeable instances, as it's a superclass of Structured

This commit also introduces new compat modules:

- Distribution.Compat.Typeable with typeRep
- Distribution.Client.Compat.Orphans,
  to collect at least some orphans into central place.
